TO ALL WHOM IT MAY CONCEKRN v Be it known that I, PETER` KENDnIoK,of Trenton, in the county of Mercer, and State of New Jersey, have invented a new and useful Improvement in Machines for `lilattening and Bending Rods for Chain-Links; and I kdo hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference lbeing had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side sectional view of my invention, taken in the line :u x, fig. 2.

Figure 2 is a plan or top view of the same.

Figure 3 is a part view of a portion of the same.

Similar letters of reference indicate like parts. t

This invention relates to a. new and improved maehinelfor flattening and bending rods for the manufacture of links for chains, such as are used more especially for mining purposes.

The invention consists in a peculiar construction and arrangement of parts, whereby the two diferentsized links required for the manufacture of each chain-may have the rods of which they are formed flattened and bent on one and the same machine.

A represents a horizontal bed or platform, which 'is supported at a suitable height by legs a,'or any proper framing, and B B are two upright side pieces, secured to the bed or platform, and having a shaft, C, between their upper `parte.

The shaft C has a. pulley, ax, upon it, around which abelt, b, passes, said belt also passing around a pulley,

c, on a shaft, D, underneath the bed orplatform A, C being the driving-shaft, and communicating, by means of the belt b, motion to the shaft D.

4 The shaft O has a fly-wheel, E, keyed uponit, and also an eccentric, F, to which the upper end of a rod, i is applied, the lower end of saidrod being pivoted to a cross-head or slide, H, the ends of which are tted, in

suitable guides, I I, onthe hedor platform A, near one end ofthe same.

To this cross-head or slide H there is attached a. plunger-rod, J, ivhich is fitted and vworks in a guide, K, on the bed or platform, thev inner end of `the rod Jbeing provided with a rectangular head, Ii, rounded at its end, andwhich works between two rollers M M, on the b'ed or platform., I

On the platform, near the opposite end thereof, there is a. similar device, Hbeing'the cross-head or slide, J the plunger-rod, K the guide for the same; M" M', the rollers, and II the guides for the dross-head or slide J, the latter being operatedfrom a crank, N, on the shaft D, by a connecting-rod, O.

On one end of.the shaft Cthere-is an eccentric P, which communicates a rising and falling motion to a die, Q, which is fitted in a suitable guide, VR, attached to .the upright, B.

' This die is directly over a bed or bolster, S, and the face ofthe die and the upper surface of the bolster are grooved or hollowezl out, assliown at d, in iig. 3. v

The operation of the machine is as follows: The rods, shown in red, are cut of a suitable length, properly heated and placed, one at time, on the` bed or bolster S, the centrali-*od beingin line with the grooves d d, in the die and bolster. I

Each time the die Q descends, it ilattens the rod at each'side of its centre, the centre notbeing touched in consequence of the grooves d d, and therefore left of a. cylindrical form, the original shape of the rod.

The rod, after being thus flattened, is,- undcr the same heat, placed Vin front of the plunger-rod J or J', and, as the latter is moved inward, the rod is bent so that the centre cylindrical part will be of semicireular form, and the thus attened sides parallel with each other, (seeiig. 2.)

Theplinks, after being thus attened and bent, are ready for interlocking and welding, to'oc'mplete or form the chain. l Y i One of the plunger-rods Jhas a smaller head than the other, and said rod J also has a. shorter stroke, so that it may bend rods for the smaller links of the chain; the other plunger-rod J bending rods for the larger links, two di'erent-sized links being used in each chain, as previously alluded to.'

Hziving thns described my invention, I claim as new, and desire to secnre by Letters Pctenti 1.I The arrangement of the plungers J J', rolls M M. ,guide`s K K', I I,=crossheads H H', connecting-rods O G, shafts C D, yeecentrics P F, crank N, dies Q S, and guide R, with relation to the bed A, substantially as herein shown and described, for the purposes,v specified.

2. The combination of the grooved .dies Q S, arranged as described, withthe bending-mechanism, all suby stantially as set forth.
